IMPROVEMENT IN HUBS AND AXLES.

Specification forming part of Letters Patent No. 111,822, dated February14, 1871.

To all whom it may concern:

Be it known that I, CARLOS R. DONNER, of Sonora, county of Tuolumne,State of California, have invented an Improved Wagon- Axle and I dohereby declare the following description and accompanying drawing aresufficient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovements without further invention or experiment.

The object of my invention is to provide an improvement in the axles andaxle-boxes employed on wagons and carriages; and it consists, first, inan improved manner of uniting the steel spindle with the iron portion ofthe axle, and also in the formation of a sort of hub on the holding-nut,which hub can be shortened, so as to bring the nut closer, and thuscompensate for any end wear of the box.

My invention further consists in the use of secondary steel boxes withinthe main axlebox, and a series of oil-cups is arranged on the hub and anouter nut, which open at various points within the box.

A cap and protecting-ring are secured at the outer and inner ends of thehub, respectively, to protect from dirt.

Referring to the accompanying drawing for a more complete explanation ofmyinvention, Figure l is a longitudinal section of my axlebox, showingthe axle. Fig. 2 is a perspective view of the cap.

A is a hub, containing an axle-box, B, within which the axle turns. Thisbox is provided at its inner end with one oil-cup or opening, 0, insmall wagons, and with two, as at D, if the wagons be large, andpassages from these cups open at various points within the box, so as tothoroughly lubricate the spindle 1* Within the box 13, near each end,are two steel supplementary boxes, to a, which the spindle E bears in asit turns, and these are also pierced with holes for lubricating. The nutF, which serves to retain the wheel in place 011 the spindle, has a sortof hub or spindle, b, which extends inward, and rests against theshoulder at the end of the spindle, as shown. The threads of the screw 0are only cut in the outer part of the nut, the shoulder not beingprovided with any threads, so that when the parts wear and allow toomuch end motion the end of the shoulder b can be filed 01f, sothat thenut will turn up closer, and thus compensate for the wear. An oil cup orhole, (I, may also be provided 011 the nut with a passage, as shown.

The different oilers may be closed by corks or other suitable devices.

In order to protect the moving parts from dust or dirt, a band or cover,G, is fastened to the inner end of the wheel, and extends over thecollar. At the outer end is a cap, H, which fits over the nut F, and issecured by means of two lugs, c c, at the lower side, which enterstaples or loops At the upper side is a catch, m, which is operated by aspring and looks into a slot at a, after which it may be secured by aset-screw, o.

The spindle E may be made of steel, and is drawn out to a wedge shape,as shown at I, and has a double collar, as at K.

The iron portion of the axle J is made to clasp this wedge, and iswelded so as to extend under the collar, thus making a strong joint, andit can be rapidly done with less labor to the blacksmith than in theordinary method of welding.

By this construction of axle and box I am enabled to build wheels whichwill last a long time without running loose, and by means of thepeculiar nut the end motion can be taken up when it becomes too great.

Having thus described my invention, what I desire to secure by LettersPatent is- The box 13, with its interior constructed as described, andhaving the supplemental steel boxes a a, in combination with theoil-cups O and D, the holding-nut F, with its projecting hub or shoulder11, and the cap H, with its lugs c c, all constructed and arrangedsubstantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand and seal.

CARLOS R. DONNER.
